Everything came back nice but I kept them dry lotted in Jan, Feb and most of March to keep them from picking it clean. We also had an early growing spurt which gave us grass early. I live in MO and we're having a rainy season that is making up for our loses last year. Really I ran out sooner than that but they would still pick at it without leaving dirt and I didn't feel I had to pull them off to save my pastures till about Jan. I ran out of anything to eat about November and had to supplement till April. This spring I had 25 lambs with those ewes and like you they aren't making a dent. They naturally rotated from the cool weather clover field in the spring and early summer to the one with the warm weather grass later.

I ran 13 ewes and 2 rams on 17 acres with no fencing but 2 separate fields, one warm weather grass and 1 cool weather grass. And I'd bring them off so that you didn't over graze as needed. No matter what, when you hit your dry season and winter with those numbers and that small a spot you are going to have to supplement.

If you watch closely, move them as quick as you need to, as soon as you see them eating more than is growing. Which isn't that bad a thing if you can find cheap hay. I'm thinking 10 acres cut into 2 tracts might get you a while if you were letting them graze 1 tract per week but then you'd get to the summer slow down or winter no growing and you'd be left supplementing your cows. You might not be making a dent in it now but in a few months they will pick each lot clean rather quickly. Let's say you have 10 acres for 4 cattle and cut it into small 1 acre plots.
